[Summary of the lecture] This course covers the fundamental concepts of organometallic chemistry through the chemistry of various ligands commonly used for the organometallic complexes, such as alkyls, hydrides, carbonyls, phosphines, alkenes, and alkynes.
[Aim of the lecture] Since the nature of ligands coordinated on a transition metal center highly affects the properties of transition metal complexes, studying the roles of ligands is important for understanding the reactivity of transition metal complexes as well as designing novel reactions using organometallic complexes as a catalyst. This course focuses on the fundamental chemistry of the individual ligand commonly used for the organometallic complexes. Students understand the fundamental feature of organometallic complexes different from classical Werner type complexes through the systematic consideration of various types of ligands.
At the end of this course, students will be able to:
1) Explain the π-interaction of d-orbitals and ligands.
2) Explain the 18-electron rule.
3) Explain the synthetic methods and reactivity of alkyl and hydrido complexes
4) Explain the properties of carbonyl and phosphine complexes.
5) Explain the properties of alkene and alkyne complexes.
Ligand field theory, the 18-electron rule, alkyl complex, hydrido complex, carbonyl complex, phosphine complex, alkene complex, alkyne complex, σ-complex, π-complex, donation and back donation
|✔ Specialist skills||Intercultural skills||Communication skills||Critical thinking skills||Practical and/or problem-solving skills|
This lecture will proceeds in the following order: (1) interaction of d-orbitals with ligands, (2) chemistry and properties of individual ligands, such as alkyl, hydride, and carbonyl ligands. In the last day, final examination is set to assess the level of understanding
|Course schedule||Required learning|
|Class 1||The Ligand-field theory and the 18-electron rule||Explain the interaction of d-orbitals with ligands and explain the electron counting of a complex by using 18-electron rule..|

|Class 7||Practice problems to assess the level of understanding and explanation of the answers||Understand the course contents and solve practice problems.|
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Final examination (70%), level of class participation (30%) which is assessed by small quizzes and so on.
No prerequisites are necessary, but enrollment in the related courses (Inorganic Chemistry (Theory II) (CAP.A372) and Inorganic Chemistry (Coordination Chemistry) (CAP.A373)) is desirable.
